. Use 20 ozs. of oil. For type and grade of oil to use, see"ENGINE" in Customer Responsibilities section of thismanual.

Pour oil slowly. Do not over fill.Check oil level before each use. Add oil if needed. Fillto full line on dipstick.

To read proper level, tighten engine oil cap each time.

o Reinstall engine oil cap and tighten.

After the first two (2) hours of mowing, change the oil,and every 25 hours thereafter. You may need tochange the oil more often under dusty, dirty conditions.

GAS (See Fig. 9)

Fill gasoline tank with fresh, clean, unleaded gasoline,DO NOT USE PREMIUM GASOLINE. BE CAREFULNOT TO OVER FILL TANK.

WARNING: Experience indicates that alcohol blendedfuels (called gasohol or using ethanol or methanol) canattract moisture which leads to separation and formation ofacids during storage. Acidic gas can damage the fuelsystem of an engine while in storage. To avoid engineproblems, the fuel system should be emptied before stor-age of 30 days or longer. Drain the fuel tank, start theengine and let it run until fuel lines and carburetor areempty. Use fresh fuel next season. See Storage Instruc-tions for additional information. Never use engine orcarburetor cleaner products in fuel tank or permanentdamage may occur.

MOWING TIPS

o

o

Under certain conditions, such as very tall grass, it maybe necessary to raise the height of cut to reducepushing effort and to keep from overloading the engineand leaving clumps of grass clippings.

For extremely heavy cutting, reduce the width of cutand raise the rear of the lawn mower housing one (1)wheel adjuster setting higher than the front for betterdischarge of grass.

For better grass bagging and most cutting conditions,the engine speed should be set in the fast (,_) position.

When using a rear discharge lawn mower in moist,heavy grass, clumps of cut grass may not enter thegrass catcher. Reduce ground speed (pushing speed)and/or run the lawn moweroverthe area asecond time.

Ifa trail of grass clippin gs is left on the right side of a reardischarge lawn mower, mow in a clockwise directionwith a small overlap to collect the clippings on the nextpass.

Keep top of engine around starter clear and clean ofgrass clippings and chaff. This wil! help engine air flowand extend engine life.

Pores in cloth grass catchers can become filled with dirtand dust with use and catchers will collect less grass.To prevent this, regularly hose catchers off with waterand let dry before using.

OPERATION

MULCHING MOWING TIPSIMPORTANT: FOR BEST PERFORMANCE, KEEPMOWER HOUSING FREE OF BUILT-UP GRASS ANDTRASH. SEE "CLEANING" IN CUSTOMERRESPONSIBILITIES SECTION OF THIS MANUAL.

The special mulching blade will recut the grass clip-pings many times and reduce them in size so that asthey fall onto the lawn they will disperse into the grassand not be noticed. Also, the mulched grass willbiodegrade quickly to provide nutrients for the lawn.Always mulch with your highest engine (blade) speedas this will provide the best recutting action of theblades.

Avoid cutting your lawn when it is wet. Wet grass tendsto form clumps and interferes with the mulching action.The best time to mow your lawn is the early afternoon.At this time the grass has dried and the newly cut areawill not be exposed to the direct sun.

For best results, adjust the lawn mower cutting heightso that the lawn mower cuts off onty the top one-thirdof the grass blades (See Fig. 10). If the lawn isovergrown it will be necessary to raise the height of cutto reduce pushing effort and to keep from overloadingthe engine and leaving clumps of mulched grass. Forextremely heavy mulching, reduce your width of cut byoverlapping previously cut path and mow slowly.

Certain types of grass and grass conditions may re-quire that an area be mulched a second time tocompletely hide the clippings. When doing a secondcut, mow across or perpendicular to the first cut path.

Change your cutting pattern from week to week. Mownorth to south one week then change to east to west thenext week. This will help prevent matting and grainingof the lawn,
